Abstract
This paper presents a case study of cliff retreat and the progressive development of talus deposits in the vicinity of the Hungtsaiping rockfall area of Taiwan. Geomorphologic analysis and physical modeling identified the types involved in cliff retreat as parallel rectilinear slope retreat transforming to central rectilinear slope retreat. Cliff retreat and talus deposition patterns in Hungtsaiping can be categorized as follows: (1) simultaneous retreat with steep slope; (2) simultaneous retreat with gentle slope; (3) central rectilinear slope retreat with steep slope; (4) central rectilinear slope retreat with gentle slope; (5) parallel rectilinear slope retreat with steep; and (6) parallel rectilinear slope retreat with gentle slope. This paper identifies the fundamental control factors associated with cliff retreat and proposes a possible scenario to explain cliff retreat and the progressive development of talus deposits in the Hungtsaiping area from 1904 to 2006.
